"From the Studebaker Shop Manual it shows the following 4 connections to the OD Relay. In testing this circuit I did the last test in the OD relay trouble shooting guide where you ground out the OD governor wire, turn the car key on, and check for current on the unconnected SOL terminal. In this configuration, you should be reading 6 volts (the car isn't running right?) going into the 20 amp fuse, 6 volts coming out of the 20 amp fuse, and about 5.8 volts coming out on the SOL terminal. The table below summarizes the connections."
BAT #10 gauge Black Wire Connects to Pin#87 on relay
SOL #10 gauge Red Wire Connects to Pin#30 on relay
IGN #16 gauge Red/Yellow Wire Connects to Pin#86 on relay
THSW #16 gauge Green Wire Connects to Pin#85 on relay
